While I think the Laver S is a great racket, I don't think the others are copies of it. I think several of them came out BEFORE the Laver Type S. The Instinct is no where near as stiff either. The Surge doesn't feel at all like a Laver S, even though its the same head size, and it too, isn't as flexible as the Instinct. Also, the Head has a more dense string pattern. The Laver S is probably the best volleying, and most solid feeling of the bunch.

They are excellent racquets; good power on serve + good stability on ground strokes and the net. They're nicely balanced at about 6 pts head-light. You will not be disappointed. My only advice is to string them with something decent, (like Babolat VS 17 Natural Gut 8) ) and string savers don't hurt either.

I also recommend that you stay as far away as possible from pathetic head-heavy racquets. Although some might be listed as "tweeners", I consider them all to be game-improvement types.

The X5 is head-heavy and too much of a "game-improvement" racquet. Unless you have serious problems generating pace I would recommend you stay FAR away from any "X" or "Hammer" series racquets...Head-Light is the way to go 8)

yeah, most high school kids are strong enough not to use a powerful racquet. If you still want a head heavy one, the wilson 5.3 is pretty good. I used it my whole sophomore year and had pretty good results. But I saw they light and went for a players racquet. The one I'm using is the LM prestige MP and it is an awesome frame.
